75W-80 GL4 Gear Oil
75W-80 GL4 gearbox oil for Land Rover manual gearboxes requiring MTF-94, including R380 applications. This section includes Ravenol fully synthetic MTF-94 in 1L and 4L packs alongside Genuine Land Rover MTF-94 in a 5L container.
Choose the oil by the gearbox and required specification rather than viscosity alone. MTF-94 is used in many Land Rover manual gearbox applications, but it is not interchangeable with the oils used in LT230 transfer boxes, differentials or the later Defender Puma MT82 gearbox.

75W-80 GL4 oil for MTF-94 gearboxes
This category brings together 75W-80 manual gearbox oils for Land Rover gearboxes requiring MTF-94. The main application is the R380 five-speed manual gearbox, with Ravenol and Genuine Land Rover fluids available in different pack sizes.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Complete R380 gearbox oil change | Ravenol MTF-94 4L or Genuine Land Rover MTF-94 5L | Confirm the gearbox requires MTF-94 and check the specified service quantity |
| R380 oil change using 1L bottles | Ravenol MTF-94 1L | An R380 normally requires approximately 2.5L, so three 1L bottles are commonly needed |
| Gearbox oil top-up | Match the oil already in the gearbox where possible | Confirm that MTF-94 is already specified and do not mix unrelated gearbox oils |
| Genuine Land Rover fluid | Genuine Land Rover MTF-94 in the 5L container | Check the STC9157 fluid reference and required quantity |

Gearbox type
Confirm that the vehicle has an R380 or another manual gearbox requiring MTF-94.
